<p>Chemical equilibrium diagrams can easily be obtained using SPANA.</p>

<p>SPANA is a graphic user interface to the
<a href="SP_0_Main.htm">SED-PREDOM</a> programs which perform the calculations needed
to create chemical equilibrium diagrams.</p>

<p>SPAMA can also call <a href="DB_0_Main.htm">DATABASE</a> to make diagrams
based on equilibrium constants retrieved from a database.</p>
